{"pk":30018,"title":"Does bilingual input hurt? A simulation of language discrimination and clusteringusing i-vectors","subtitle":null,"abstract":"The language discrimination process in infants has been suc-cessfully modeled using i-vector based systems, with re-sults replicating several experimental findings. Still, recentwork found intriguing results regarding the difference betweenmonolingual and mixed-language exposure on language dis-crimination tasks. We use two carefully designed datasets,with an additional “bilingual” condition on the i-vector modelof language discrimination. Our results do not show any dif-ference in the ability of discriminating languages between thethree backgrounds, although we do replicate past observationsthat distant languages (English-Finnish) are easier to discrimi-nate than close languages (English-German). We do, however,find a strong effect of background when testing for the abilityof the learner to automatically sort sentences in language clus-ters: bilingual background being generally harder than mixedbackground (one speaker one language). Other analyses revealthat clustering is dominated by speakers information ratherthan by languages.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"language discrimination; language diarization; i-vectors; bilingualism; speaker information"}],"section":"Poster Session 3","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0q4029r5","frozenauthors":[{"first_name":"Maureen","middle_name":"","last_name":"de Seyssel","name_suffix":"","institution":"Laboratoire de Sciences Cognitives et Psycholinguistique","department":""},{"first_name":"Emmanuel","middle_name":"","last_name":"Dupoux","name_suffix":"","institution":"Laboratoire de Sciences Cognitives et Psycholinguistique","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30018/galley/19872/download/"}]}
